Ough, maybe I've gone over to the dark side. lol I still root for Walt and Skyler. Hank crackes me up, but I don't have any compassion for him or Marie. He wasn't suckered into anything. Everything that Walt got, he threw in Walt's lap, except for that time Walt bugged his office. lol That was devious. But still, he gave an unauthorized person access to his office and failed to scan it.
I guess I see things in shades of grey and I don't think Hank has enough to go after Walt. It's unlikely that he can get enough to convict Walt of anything. So basically, Hank would be ruining many lives to prosecute a dying man. What is to be gained from it? I suspect it's Hank's ego that can't stand to let it go. IF he keeps up, he could really get hurt or lose Marie.
I'm willing to accept whatever the ending turns out to be. Gilligan has not disappointed me so far, so I'll just have to accept his ending.
